To cZZ whom a: may concern]:

Be itknown that Josnrrr SALIM Prunes, of Norbury House, liianchester, England, (whose post-ofiice address is Norbury House, QO Dickinson Street. ll'lanchester, England,) has invented certain new and useful improvements in Flexible Joints for Diving Dresses, for which I have filed an application in Great Britain, Number 162, on January 2, 1920,) of which the following is a specification.

This invention for improvements in flexible joints for diving dresses relates to steel or similar rigid diving dresses which are constructed to resist the pressure of the water, at great depths and has for its ob ject, to eliminate friction inthe oints of the arm and leg coverings or other art1cu-' lated parts. so that these members shall have freedom of movement notwithstanding the pressure of the water, also to provide an improved impermeable joint having great flexibility in use. The inventionconsists in providing a fluid cushion or support between the relatively movable parts of the joint which is incompressible but readily displaceable to permit of the movements of the articulated members. i

In the accompanying sheet of illustrative drawings- Fig. 1 is a vertical section of a flexible joint constructed according, to this invention. Fig. 2 is a plan of the lowest part of same, Figs. 3and 4 are side elevations of flexible joints drawn on a smaller scale showing different pivot arrangements for the same.

As shown each joint comprises two cupshaped members a, a fitted together and adapted to slide one within the other. The joint member a has double walls forming an annular chamber or space Z) for receiving the other joint member a and also a quantity of wateror other incompressible liquid which is confined in the chamber or space aforesaid between flexible diaphragms 0. These diaphragms are formed of'rubberized fabric or other material and are clamped between separable parts of the cupshaped members which are secured by stud screws cl, bolts or other means. Other impermeable packing may be employed to confine the incompressible liquid which forms a cushion or fluid bearing between the two articulated members distributing the pres Specification of Letters Patent.

sureof the external water evenly around the joint and enabling the pressure to be compensated in such a way that there are no unbalanced forces due to external pressure of thewater tending to create friction on the, pivots-of the joint or interfering with the freedom of: movement.

at right angles Fig. 4 so as to form a universal pivot after the style of a globe of the world Of course these hinges are to hold the dress together whenit is out of the water; under, working conditions the are quite inactive, the water joint itself acting as a hinge.

Various safety devices can beapplied to prevent the rubberized fabric from getting bruised or torn to prevent anygrit getting into the joints and to protect the same against accidents in case of leakage.

i 1. A joint for a diving dress comprising two relatively movable joint members forming between their relatively movable parts.

a closed chamber, and an incompressible fluidconfined in the said chamber and adapted to insure freedom. of movement to the joint members and overcome the pressure of the water external to the joint.

' 2. In a metal diving dress a joint for insuring freedom ofmovement to the limbs at great depths, said joint comprising articu- .lated joint members, means forming a closed chamber between the said joint members, and an incompressible fluid confined inthe said chamber and adapted to form an incompressible but readily displaceable fluid bearing-between the articulated joint members.

3. A jointv for diving armor comprising articulated members, an incompressible fluid, and means for confining the fluid in the joint so as to insure freedom of movement to the articulated members.

4;. 'A flexible joint for diving dress com- Patented J an. 3,1922. I Application filed April 30, 1821. Serial No. 465,708.

prising cup-shaped members fitted together and adapted to slide one within the other,

one of said joint members having double walls forming an annular space for receiving the other olnt member and means for confining an incompressible liquid in the chamber substantially as and for the purpose described;

5. A joint for diving armor comprising cup-shaped joint members fitted together and adapted to slide one within the other, one of said joint members having double walls forming an annular space for receivconfining an incompressible fluid in the joint between inner and outer members thereof.

7 A joint of the character described comprising a member having spaced walls forming a pocket, a second member slidably fitting into the pocket and a carrier for an incompressible fluid positioned in the pocket and having its inner endportion secured at the inner end of the pocket and its outer end portion secured to the inner end portion of the second oint member whereby the flexible fluid carrier may have movement in the pocket with the second member to keep incompressible fluid confinedv between the walls of the first joint member and inner end portion of the second member.

In testimony whereof he has affixed his signature.
